Endura Flyte for me. I have found it to be breathable, surprisingly so. In winter I only use a base layer and the jacket. I have found that combo keeps me warm enough but also dry on the inside. I think they are about £100 maybe a bit less.

I have found it to be really comfortable whilst riding. It has loads of pockets and under arm zips should you get too hot. I'm a sweaty bugger so have them open even when it's cold. Personal opinion and all that but I have found the jacket will keep me dry on wet rides and warm enough (without a sweat fest) on really cold rides.

Right, I have just purchased a fairly light weight jacket from decathlon from their sailing section. It was £25 and the water proofing qualities are amazing, if it had the word 'cycling' in he title then add £75
